Booster pump recommendations for 40” membrane?

[Yuki]

Is anyone running this very large 40” membrane 4040 and what booster pump would you recommend? I’m at 50psi and need to get over 60psi preferably 70psi and still have a good gallons per minute. Thank you very much. https://www.amazon.com/×40-Filmtec-TW30-Membrane-TW30-4040/dp/B004ASI5EG/ref=mp_s_a_1_13?crid=KPHF47SE751P&keywords=4x40+ro+membrane&qid=1654621602&sprefix=40”+ro+%2Caps%2C119&sr=8-13

aquatec 8800 works for me i processabout 200 gallons a week of ro/di they are pretty cheap, we use hydrologic pumps at work that are commercially reated for full time duty if you need a continuous pump they are big bucks

I’m doing 300+ gallons per day and I found out the membrane likes 100psi. I think I’m going with this. It does up to 150psi and 13gph. It’s a beast and I couldn’t find them anywhere. Finally found one in Georgia. I hope it works and doesn’t blow my system up. https://www.pentair.com/en-us/produ...otec-fp5732-1-hp-multistage-booster-pump.html
